Adding a new young Silver Laced Polish Frissle Rooster tomorrow

I have one mature rooster, and a pretty mature second rooster, and both get along great and are gentle with the ladies, and they never fight with each other. I also have 18 adult hens and three 2.5 month old juveniles. A lady can't have roosters so we are taking him in. She says he is really sweet, but I know he is still young.

She is bringing him over tomorrow. Should I add him directly to the flock and see how he does? Or would you suggest I keep him cordoned off, and if so for how long? Or is it better to cordon him off for the rest of the day then add him to the flock tomorrow night when they are all roosting?

Thank you for your help and suggestions.

We anticipate hatching more chicks so the number work out for having three roosters, from everything that I have read here. Plus they have a large free range area and a large roosting area.

I sometimes bring bantam roosters from my bantam coop over to my large breed shed. They go in a separation pen for a couple of months, the other birds work out their issues through the wire, when I let them out finally there's no fighting, he might get chased a bit but he takes his place in the pecking order without incident. Otherwise I order fresh roosters with my chick orders, integrate at about eight weeks and the young roosters grow up in the flock and are accepted.

So I would set your new rooster up in a pen within the coop and expect it to a while before he's accepted without anyone trying to kill him.

I think the main issue is the lead rooster who had no problems with Oreo. Rooster number two got in Oreos face a little then stopped. Oreo was more the one trying to jump up in the pecking order on day one. At the end of the day they all roosted together. It was interesting that he had no interest in being cordoned off and alone, he mixed in really well.
